Question

The computer science department is making a new recruitment poster for computer science majors and would like to include information about the average salary of a software developer on the Treasure Coast. To estimate the average salary of a software developer, someone from the department collected a random sample of 10 local software developers. Their salaries are listed below. Assume that the salaries of all software developers on the Treasure Coast are normally distributed.

81,080 82,959
81,751 82,073
82,019 81,234
82,038 82,491
82,586 82,371

Determine the point estimate, x¯ and the sample standard deviation, s. Round the solutions to four decimal places, if necessary.

x with the - on top of x=

s=

Using a 95% confidence level, determine the margin of error, E, and a confidence interval for the average salary of a software developer on the Treasure Coast. Report the confidence interval using interval notation. Round solutions to two decimal places, if necessary.

The margin of error is given by E=

A 95% confidence interval is given by =
